Friday, 28th: Started about sunrise, travelled about 5 miles and stopped to take breakfast. The heat was oppressive and we were compelled to go 20 miles farther before we came to either wood or water. The stream on which we camped is a fork of the Kanzas and is well known to all the mountaineers, by the name of the Big Blue; an antelope was killed.
They are in the northeast corner of Kansas, traveling toward Nebraska. (All of this was Indian Territory at the time.) It still sounds like a typical camping trip: the weather is hot and they have to go farther than they expected to find good accommodations.
